Cheesecake brownies are the ultimate mashup chewy brownies and fluffy, tangy cheesecake swirls. The combo turns out amazing dessert bars that look super pretty and taste awesome.
My daughter once asked for something creamy and chocolatey, so we made these together. Swirling the marbled top was our favorite part—and now folks always want to know the secret.
Delicious Ingredients
- Cream cheese: Brings in that creamy cheesecake touch. Full fat blocks work best and should be nice and soft.
- All purpose flour: Fortifies the brownies. Either bleached or unbleached flour is fine here.
- Salt: Gives a lift to every bit of flavor. A fine sea salt will do the trick.
- Vanilla extract: Makes the sweetness rounder. Real vanilla works way better than the fake stuff.
- Eggs: Hold the brownies and cheesecake layer together. Large eggs at room temperature are easiest to mix in.
- Unsweetened cocoa powder: Gives the brownies even deeper chocolate flavor. Try a Dutch processed one if you can.
- Granulated sugar: Brings sweetness to every bite of both layers. Go for finer sugar if you want it to melt in fully.
- Sour cream: A little tang to brighten the cheesecake layer. Pick a thick, creamy one if you can.
- Unsalted butter: Makes brownies super fudgy and rich. Fresh, quality butter always tastes best.
- Unsweetened baking chocolate: The ultimate deep, bold chocolate base. You want that deep cocoa smell and a good snap.
Easy Step by Step
- Chill before serving:
- Let the bars set up in the fridge for a minimum of four hours. Once cold, they're much tidier to cut.
- Bake:
- Pop the pan into a fully heated oven at three-fifty degrees. Bake for about fifty to fifty-five minutes. Look for the top to puff up and lose its shine—the edges should have a hint of gold. Let them cool on the counter all the way.
- Layer and swirl:
- Pour your cheesecake stuff on top of the brownie batter. Swirl things together gently with a knife for that ripple effect—don't go overboard or you'll lose the pretty lines.
- Mix in cheesecake add ins:
- Add the eggs (one after another), then mix in sugar and vanilla. Keep mixing until everything's super smooth, not streaky.
- Beat cheesecake layer:
- In a new bowl, whip soft cream cheese with sour cream. Use a mixer to knock out all the lumps for the creamiest swirl ever.
- Add flour:
- Now fold in your all purpose flour, just until it disappears. Don't beat it too much—overmixing can dry things out. Spread your batter evenly in the pan.
- Mix in brownie ingredients:
- Stir sugar and cocoa powder into that melty chocolate. Then gradually add eggs and vanilla, sprinkling in salt last. It'll seem a little gritty but keeps smoothing out as you go.
- Melt chocolate and butter:
- Break up the chocolate and slide in butter. Microwave in short bursts and stir around until it's totally mixed and sleek. This gives you that shiny brownie finish.
- Prepare the pan:
- Set a sheet of foil in your nine-inch pan, then spray with oil. This stops anything from sticking to the sides and makes for easy cleanup.

Honestly, swirling the batters together is such a fun moment. Every time, the pan comes out with its own swirl pattern—like edible artwork. My kids never get tired of joining in for that step!
Keep Them Fresh
Put your brownie bars in a sealed container in the fridge; they'll last around three days. Stack with parchment in between so they don't stick together. For long-term storage, wrap up each bar tightly and freeze. Bring to room temp when you want, or snack on them cold straight from the fridge—my personal favorite.

Swap Outs
If you're out of sour cream, plain Greek yogurt works just as well or try mascarpone for something extra rich. For gluten free needs, go with a trusted one-for-one flour blend instead of regular flour. Skip whipped cream cheese; it's not good for swirling since it changes the texture.
How to Serve
Chill the bars well and serve plain, or brighten things up with fresh berries. Want to fancy it up? Add whipped cream and chocolate curls on top. They're also great wrapped up and gifted—just use parchment paper and some ribbon.
Behind the Swirl
Cheesecake brownies took off in the States near the end of the last century merging two favorites into one dreamy treat. The swirled top was inspired by European tortes, making the whole thing about having fun with the batter and making every square look cool.
Common Recipe Questions
- → How can I get those swirls looking awesome?
Let your cream cheese and eggs hang out on the counter till they’re not chilly anymore. Spread your cheesecake mix on top, then drag a butter knife through everything to make fun marble streaks.
- → Can I use semi-sweet chocolate instead?
Yep, semi-sweet works fine—just remember to take it easy on the sugar since that chocolate’s already got plenty.

Chilling helps the bars stay sturdy for tidy slices. Plus, it lets the flavors blend smoother.

Throw them in an airtight box in your fridge. They’ll last around three days, or freeze ’em if you want to keep them longer.
